Study Notes
Circulatory System: Blood
- Erythrocytes are the most abundant formed elements of blood, critical for oxygen transport.
- Hematoma refers to a mass of clotted blood.
- Functions of the circulatory system include stabilization of body pH, regulation of body temperature, and transportation of nutrients and gases.
- Steps of hemostasis include vascular spasm, platelet plug formation, and blood coagulation.
- Hemopoiesis is the formation of blood, producing all formed elements.
- Monocytes have characteristics including a large, clearly visible nucleus and sparse granules in the cytoplasm.
- Erythropoiesis specifically refers to the production of red blood cells.
- Albumin in plasma is responsible for solute transport, pH buffering, and regulating blood viscosity and osmolarity.
- Globulin in plasma plays a vital role in defense functions for immunity.
- Fibrinogen is responsible for blood clotting, converting to fibrin during coagulation.
- One molecule of hemoglobin contains four globin chains and four heme groups, essential for oxygen binding.
- Anemia can be caused by increased hemolysis, hemorrhage, or inadequate hemoglobin synthesis.
- Platelets are cell fragments produced from megakaryocytes, essential for clot formation.
- The process of platelet plug formation includes contact with collagen, platelet activation, contraction of pseudopods, and mass formation.
- Hemolysis refers to the rupture of red blood cells, often leading to various complications.
- Neutrophils are a type of leukocyte essential for immune defense.
- The cardiovascular system includes the heart and blood vessels, while the circulatory system encompasses all blood elements.
- Hemostasis is a physiological process that controls excessive bleeding.
- Normal erythrocytes are shaped biconcave, lack a nucleus, and contain hemoglobin crucial for gas transport.
- Eosinophils are leukocytes characterized by a nucleus with two lobes and granules that are rosy to orange in color.
- The linkage between precursor cells and their derived cells includes monocytes from monoblasts, granulocytes from myeloblasts, lymphocytes from lymphoblasts, and erythrocytes from erythroblasts.
- Erythrocytes are critical for survival due to their oxygen-transport capabilities.
- Fibrinogen is not present in serum due to its conversion into fibrin during clotting.
- Plasma carries substances including water, proteins, nutrients, electrolytes, hormones, gases, and waste.
- Viscosity describes the thickness or stickiness of the blood.
- Leukocytes are categorized as white blood cells, including various types involved in immune protection.
- The percentage of plasma in blood is approximately 47-63%, while hematocrit is 37-52%, and the buffy coat is about 1% or less.
- Factors like low blood pressure and edema can result from decreased blood osmolarity.
- Iron is necessary for synthesizing hemoglobin, the oxygen-carrying protein in red blood cells.
- Hemophilia is an inherited disorder caused by a deficiency of clotting factors, more common in males.
- Leukopoiesis refers to the production of white blood cells, essential for immune response.
- Mechanisms to prevent inappropriate blood clotting include platelet repulsion and the dilution of clotting factors.
- Fibrinolysis involves a series of steps that dissolve blood clots, beginning with the conversion of prekallikrein to kallikrein.
- Plasma proteins are produced predominantly in the liver, with components obtained from digestion and synthesis.
- Leukemia is a cancerous condition resulting in an excess of leukocytes and precursors in the blood.
- Erythropoietin stimulates red blood cell production and is released in response to low oxygen levels.
- Sickle cell disease arises from a hereditary defect in hemoglobin, affecting red blood cell shape.
- Blood viscosity can be reduced by factors like protein deficiency or decreased hematocrit.
- The production of white blood cells follows a hierarchical process from hemopoietic stem cells to mature cells.
